The graph describes the motion of an object. 1. The object moves with _ from A to B.

2. It _ from B to C.

3. It moves with _ from C to D.

Options for 1st
constant acceleration
positive acceleration
constant velocity

Options for 2nd
remains stationary
it slows down
it speeds up

Options for 3rd
constant acceleration
positive acceleration
constant velocity

1. The object moves with constant from A to B.

2. It remains stationary from B to C.

3. It moves with constant velocity from C to D.

Explanation:

Position vs Time Graph

It shows the change of position of a body over time. If the graph is an increasing line, then the object has positive speed, if it's a decreasing line, it has negative speed, if it's a horizontal line, it's at rest.

The first part of the graph (from A to B) shows an increasing line, which means the object has a position that increases in time, thus the speed is positive and constant.

1. The object moves with constant from A to B.

The second part of the graph shows a horizontal line, which means the object does not change its position in time. It's at rest.

2. It remains stationary from B to C.

The third part shows the object has started to move again with positive and constant speed because the graph is a line:

3. It moves with constant velocity from C to D.
